uber/h3-py

This system is a Python library providing high-performance bindings for the H3 geospatial indexing system. It exposes H3 functionality through a modular API that supports multiple data backends, including standard Python types, memory views, and NumPy arrays. The core implementation has been optimized using Cython for vectorized operations, while the project's build infrastructure has been modernized to support C extensions and streamlined development workflows.

About this page

  • The description of this project is derived from its own commit history, not from its README.
  • The score is its highest published measurement, taken on 4 August 2026 at a pinned commit. It is not a live figure and does not change until the project is measured again.
  • Measured at commit d44676e44f — the exact code this score is about.
  • Scored under rubric rubric-2026.08.19. Score the same commit under that rubric and you get the same number.
